COMBINED CIRCUIT BREAKER AND DISTRIB'UT'ER.

Specification of Letters Patent. Patented Aug, 2'7, 1912.

Application filed April 18, 1910. Serial 110. 556,216.

To all whom it may concern:

Be it known that I, CARL A. PFANSTIEHL, a citizen of the United States of America, and a resident of Highland Park, in the county of Lake and State of Illinois, have invented certain new and useful Improvements in Combined Circuit Breakers and Distributers, of which the followlng 1s a specification. I

This invention relates to a combined circuit breaking and distributing mechanism for the high tension electric current employed in electric ignition systems of internal combustion engines of motor cycles and the like. And the present improvement has for its object to provide .a simple and efiicient construction of parts adapt:

, in an eccentric posltion 1n the casing 4 aforeed to afford an effective breaking of the electric circuit at the proper periodsi in the cycle of the engine in the passage of v the current to the induction coil and condenser, and the subsequent distribution of the high tension current from said induction f coil and condenser to the sparking terminals of engine and at the proper intervals and without liability to short circuit through the metal or grounded parts of the apparatus,

roller l3incontact with the cam disk 8,

all as wili hereinafter more fully appear.

In the accompanying drawings :-Figure 1, is a longitudinal sectional elevation on line 02-h), Fig. 2. Fig. 2, is a transverse sectional elevation on line af-a', Fig. 1. Fig. 3, is adetail' end elevation of the revolulole' the extension pocket 6-aforesaid, to provide member of the distributor.

Similar reference numerals indicate like;

ber of the contact breaking mechanism new parts in the different views.

Referring to the drawings, l represents one end of a drivin shaft rotating in unison with the shaft 0 an internal combustion engine, through any ordinary connection therewith. I

2 is an axially orificed hub, preferably formed of an insulating material, and fitting upon'the end of the shaft 1 as shown so as to turn therewith. Said hub at its free end carries an axial shank or extension 3, for carrying the operating cuit breakin mechanism and the revoluble member of t e current distributing mechanism, hereinafter described in detail.

4 isa shell or casing formed with a sleeve 5, in. which the hub 2, aforesaid fits and turns, and with a lateral extension or pocket 6, which in conjunction with the cavity of the main portion of thecasing provides an elongated chamber for contaimng the circuit cam disk of the cir-- breaking mechanism of the present improvement.

7 is a secondary shell or casing open at its back and fitting an opening in the front of the shell or casing 4, above described, so as to be carried thereby. Said casin 7 is formed of suitable insulating maternal and is adapted to inclose the revoluble member of the high tension circuit distributing "mechanism.

8 is the cam disk before referred to as carried by the shank 3; said cam disk will usually have two opposed peripheral depressiens 9 for alternately movin the vibrating member of the circuit brea er.

10, is the vibrating member or arm above referred to, and which is pivoted at one end said, while at its other end it carries a re-. silient tongue or reed 11, and contact button or head 12, as shown. I

13 is a roller carried by the vibrating arm 10 intermediate its length and adapted to have bearing contact with the periphery of the cam disk 8, and operative engagement with the cam depression 9 of the same.

14 is a leaf spring tending to hold the and the tongue 11 in electrical contact with the adjustable contact member or screw hereinafter described.

15 is an elongated plug 'of insulating material let into an opening in a side wall-of an insulated support for the stationary mean to be described. 1

16 is an adjustable screw bolt-constituting the stationary contact member above referred to, and having a screw-threaded bearing in the plug 15 aforesaid, as well as in a conducting plate 17 carried in an insulated manner on said plug.

18 is a screw bolt securing the conducting plate 17 in place on said plug and constituting a terminal attachment for the described circuit breaking mechanism and the stationa contact 16 thereof.- The companion termlnal, inelectrioal connection with the contact tongue 11, will usually bev made on the exterior of the casing 4, the current passing through the spring 14 to said tongue 11.

19 is a hub of insulating material fitted upon the end of the axial shank 3 of the hub 2, before described, and turning therewith. Said hub constitutes the revoluble member plate orv segment 20, which passes outwardly through an annularrim 21 on the forward end of the hub 19, as shown. Said "rim 21 provides a protecting shield adapted to retard the accumulation of extraneous conducting matter on the surface of the hub 19,

intermediate of the hereinafter described for attachment of a line conductor from a contact members of the high tension current distributor. In addition said rib provides a central cavity in which the central portion of the contact segment 20 is exposed for conducting contact withthe spring plug herein after described I f In the preferred form of the present invention, the main portionof the hub19 moves in a reduced bore 22 in the forward portion of the aforesaid distributer casing 7,while at its rear portion it carries a peripheral collar23, moving in an enlarged bore at the rear of the casing 7, and in connection with the shoulder formed by the intersection of the two bores provides a circuitous or baiile gap to effectively prevent a short circuit between the contact members of the distributer and thev adjacent metal parts of the 2a is anaxially. arranged bushing in the forward head of the distributor casing 7 and having atits outer end a terminal post 25 secondary coil and condenser, while its inner tubular end constitutes a guide for the spring actuated plug 26 which has bearing against the inner portion of the contact segmerit 20 before described.

2? are a series of radial contact bars secured in and'passing through the wall of the reduced bore 22 of the distributer casing 7 with their inner ends in the path of, an adapted for serial contact with thejcontact se eat 20 aforesaid, The outer ends of said bars are'connected in any usual manner with lines extending to the spark ng terminals of an internal combustion engine.

Having thus fully described my said ina sence vention what I claim as new and desire to secure by Letters Patent, is

1;. In a combined circuit breaker and distributer for internal combustion engines, the a rim a distance from the front end of the same, the annular rim beingadapted to afford a protecting shield between the contact members of the high tension current distributer, substantially asset forth.

2. In a combined circuit breaker and dis-' tributer for internal combustion engines, the combination of'a shaft adapted for rotation in unison with'the engine, a casing arran "ed at one end of said shaft, a circuit breaking mechanism arranged in said casing and having an operating cam connected to said 7 shaft, a secondary casing secured to the cas-. ing aforesaid and formed with a reduced outer bore and an enlarged rear bore communicatin-g with the containing chamber of the circuit breakingmechanism, and a distributer mechanism arranged in said second ary casing with its revoluble member connected to said shaft, the said revoluble member having a peripheral collar arranged ad: jacent to the intersection of the two bores of the ilsecondary casing, substantially as set fort a Signed at Highland Park, Ills, this 5th day of April 1910,
